Title: Measuring system of frequency versus phase characteristic or transfer function
Inventor: NISHIJIMA TAKASHI
IPC: G01R27/28
Filed: 1981-11-16
Abstract: PURPOSE:To easily measure a transfer function and the like, by transmitting a measuring signal, and forming a comparison signal in synchronizing with the measuring signal, based on the successional period signal. CONSTITUTION:A broad band M series pseudo random pulse generating circuit 6 is connected to a recording input terminal IN of a VTR5, a reproduced output terminal OUT of the VTR5 is connected to the 2nd channel CH-B of an FET analyzer 2 via a sample hold circuit 9 and to the 1st channel CH-A via a recording signal reproduction circuit 7 and a sample hold circuit 8. Since the VTR5 can not peform recording and reproduction at the same time, an M succession pseudo random pulse is recorded as the measuring signal and reproduced and a recording signal reproduced based on this reproduced output signal, and the reproduced output signal itself, that is, comparison signal consisting of the M succession pseudo random pulses are inputted to the FET analyzer 2, allowing to measure the frequency versus phase characteristics of the VTR5 based on the comparison of the both.

Title: Gradation-representing system for led printer
Inventor: AMAYA MIKIO
IPC: G06K15/12
Filed: 1987-07-24
Abstract: PURPOSE:To realize presentation of gradations while maintaining an image density without increasing the linear density of light-emitting segments of light-emitting diodes, by forming each light-emitting segment in a size equal to 1/N times the conventional size in the feeding direction of a photosensitive body, while equally dividing one picture element into N divisignal dots arranged along the feeding direction of the photosensitive body, and exposing as many divisional dots as required by the gradation to be represented by the picture element. CONSTITUTION:For example, one picture element 33 is constituted of 4X4(=16) recording picture elements 34, each of which is divided into four divisional dots 35. An LED array 37 comprises electrodes and light-emitting elements arrayed on a substrate 38, the light-emitting elements 40 having the same width and same linear density as those in a conventional system. The height of each of the light-emitting elements in the LED array is set to be 1/4 times the corresponding size H in the conventional system, namely, so set that exposure for the vertical size of the recording element equal to 1/4 the exposure size in the conventional system can be performed in a predetermined time of t/4. Such a reduction in the height of the light-emitting elements instead of increasing the linear density of the elements in the width direction thereof can be performed relatively easily, whereby 16X4(=64) gradations can be represented.

Title: Active silencer
Inventor: NISHIKAWA KOZO
IPC: G10K11/178
Filed: 1994-08-05
Abstract: PURPOSE:To decrease a calculation quantity by decreasing the number of transformations of Fourier transform at the time of forming antinoise signals. CONSTITUTION:This active silencer has plural band-pass filters 22 which separate the primary noise signals from a primary noise detecting microphone 9 to frequency components desired to be decreased, a Fourier transform processing section 25 which subjects the digital residual noise signals of an A/D conversion section 24 to Fourier transform and extracts amplitude values and phase values in the respective frequency-components of the residual noise signals and an antinoise signal forming section 26 which forms the antinoise signals in accordance with the primary noise signals of every frequency-component from a multiplexer A/D conversion section 23 and the residual noise signals subjected to a frequency decomposition by the Fourier transform. This antinoise signal forming section 26 forms the antinoise signals in a time region without making Fourier transform of the primary noise signals and, therefore, the number of times of the Fourier transform is necessitated to be just one time of the residual noise signals to be executed by the Fourier transform processing section 25. The calculation quantity is thus decreased.
